Abstract

Example embodiments presented herein are directed towards source (401A) and target (401B) base stations, and corresponding methods therein, for providing a handover for a sub-set of bearers associated with a wireless terminal (101) being served by the source base station (401A), wherein at least one bearer of the wireless terminal remains connected to the source base station. The sub-set of bearers is less than or equal to a total number of bearers associated with the wireless terminal.
